Help / Problems Forum

Okay, so I recently got a headset to use when I play online in Halo: Reach. The only problem is, I can't hear anybody else. I checked all the boxes so I should be able to hear the other players, but I still can't hear anybody. I know my headset is working because on the corner of the screen there's a little signal that pops up every time I talk, but I still can't hear anybody. Is there something I'm doing wrong?
